1、 Hydroponic method

1. Choose hydroponic Dendrobium candidum

Before hydroponic culture, the plants suitable for hydroponic culture should be selected first. The seedlings of Dendrobium candidum that have grown for more than 2 years and have been domesticated are the best, or some branches and flower buds on the old plants can be cut off

2. Treatment of hydroponic plants

Wash the selected plant carefully, wash the soil off it, and cut off the rotten, old or diseased roots. Then soak it in the solution with carbendazim to prevent the root wound from being infected by bacteria. After disinfection, put it in a cool place to dry, and then hydroponic culture can be carried out

3. Prepare hydroponic container

When selecting hydroponic containers, it is best to use bottles with good transparency and a neck on the bottle, because in this way, Dendrobium candidum can be fully integrated into the water. If such bottles cannot be found, they can be fixed with adhesive tape

4. Hydroponic culture

Put the prepared hydroponic plants in the bottle, and then you can add water to it. Some plant nutrient solutions can be appropriately added to the water, usually amino acids or enzymes, apple vinegar can also be used, but no matter which one, you can't put too much, just a small bottle cap. If you don't want to use these, you can also buy nutrient solution directly

5. Change water and nutrient solution in time

During hydroponics, pay attention to changing water and nutrient solution regularly. If it is spring, it is best to change it in 7 to 10 days. If it is winter, it can be separated by a longer time, because the temperature is low and the plant consumes less nutrition. It is best to change it in about 15 days. In summer, it has a large amount of breathing and fast nutrient consumption, so it needs to change the nutrient solution and water every 4 to 5 days in order to hydroponic it

2、 Precautions

When hydroponicing it, it should be noted that the root cannot be completely left in the water, and two-thirds should be left outside. In addition, good ventilation conditions should be ensured
